Transmitter Antenna (from Section 7.1.2 RSS-Gen,

Issue 3, December 2010): User manuals for transmit-

ters shall display the following notice in a conspicuous

location:

The above notice may be affixed to the device instead

of displayed in the user manual.

User manuals for transmitters equipped with detach-

able antennas shall also contain the following notice in

a conspicuous location:

Immediately following the above notice, the manufac-

turer shall provide a list of all antenna types approved

for use with the transmitter, indicating the maximum

permissible antenna gain (in dBi) and required imped-

ance for each.

4.2.2 APPROVED EXTERNAL ANTENNA

TYPES

Transmitter Antenna (from Section 7.1.2 RSS-Gen,

Issue 3, December 2010):

The RN171 module can only be sold or operated with

antennas with which it was approved. Transmitter may

be approved with multiple antenna types. An antenna

type comprises antennas having similar in-band and

out-of-band radiation patterns. Testing shall be per-

formed using the highest gain antenna of each combi-

nation of transmitter and antenna type for which

approval is being sought, with the transmitter output

power set at the maximum level. Any antenna of the

same type having equal or lesser gain as an antenna

that had been successfully tested with the transmitter,

will also be considered approved with the transmitter,

and may be used and marketed with the transmitter.

When a measurement at the antenna connector is

used to determine RF output power, the effective gain

of the device's antenna shall be stated, based on mea-

surement or on data from the antenna manufacturer.

For transmitters of output power greater than 10 milli-

watts, the total antenna gain shall be added to the mea-

sured RF output power to demonstrate compliance to

the specified radiated power limits.

Modular approval testing of the RN171 module was

performed with the antenna types listed in Table 3-1.

4.3 Europe

The RN171 module is an R&TTE Directive assessed

radio module that is CE marked and has been manu-

factured and tested with the intention of being inte-

grated into a final product.

The RN171 module has been tested to R&TTE Direc-

tive 1999/5/EC Essential Requirements for Health and

Safety (Article (3.1(a)), Electromagnetic Compatibility

(EMC) (Article 3.1(b)), and Radio (Article 3.2) and are

summarized in Table 4-1. A Notified Body Opinion has

also been issued. All test reports are available on the

RN171 product web page at http://www.microchip.com.

Under Industry Canada regulations, this radio trans-

mitter may only operate using an antenna of a type

and maximum (or lesser) gain approved for the

transmitter by Industry Canada. To reduce potential

radio interference to other users, the antenna type

and its gain should be so chosen that the equivalent

isotropically radiated power (e.i.r.p.) is not more than

that necessary for successful communication.

Conformément à la réglementation d'Industrie Can-

ada, le présent émetteur radio peut fonctionner avec

une antenne d'un type et d'un gain maximal (ou

inférieur) approuvé pour l'émetteur par Industrie

Canada. Dans le but de réduire les risques de brouil-

lage radioélectrique à l'intention des autres utilisa-

teurs, il faut choisir le type d'antenne et son gain de

sorte que la puissance isotrope rayonnée équiva-

lente (p.i.r.e.) ne dépasse pas l'intensité nécessaire

à l'établissement d'une communication satisfaisante.

This radio transmitter (identify the device by certifica-

tion number, or model number if Category II) has

been approved by Industry Canada to operate with

the antenna types listed below with the maximum

permissible gain and required antenna impedance

for each antenna type indicated. Antenna types not

included in this list, having a gain greater than the

maximum gain indicated for that type, are strictly pro-

hibited for use with this device.
